3 Claims.

' a rackwhereby the operator can better concentrate on the operation of the machine.

More specifically, the invention comprises the provision of a rack for holding successive shoe parts placed adjacent to the work receiving portion of the machine and movable along with the operation of the machine to continually present an empty shoe receiving member at the same point.

In the accompanying drawing illustrating a selective embodiment of the invention- Figure 1 is a front elevation of a machine for applying cement to shoe soles and a movable rack associated therewith together with mechanism for operating the machine and the rack simultaneously.

Figure 2 is an' enlarged detail of a portion of the rack and its moving mechanism and is taken approximately on the line 2-2 of Figure 1.

Figure 3 is a detail horizontal section taken on 0 the line 3-3 of Figure 1.

Figure 4 is a view of a shoe sole or insole upon which the machine operates and which is to be stored temporarily in the rack.

The cement applying machine includes a stand- 35 ard I supporting a casing 2 for housing and providing bearings for gearing which drives a series of rollers 3. Adjacent to rollers 3 is a discharge nozzle 4 of a cement feed device including a conduit 5, a pressure gauge 6, and a control lever 1.

40 The roller mechanism is driven by the belt 8 leading from a speed reducer 9 operated by motor l0. At the left of the machine is an elongated vertical angular framing ll providing vertically spaced bearings l2 for the shafts for sprockets i3 45 which mount an endless chain M. The rack R. comprises a pair of side members l5, upper and lower cross members l6, and a plurality of wire Vs I'I having their ends seated in side members l5 and projecting outwardly therefrom to form a 50 series of shelf members, one above the other, each adapted to receive one of the shoe soles S.

The upper cross member l6 of the rack has a hook it whereby the rack may be readily attached to or removed from any link of the chain 55 ll. Framing angles ll form tracks for receiving and guiding side members is. of the rack ar the latter moves with chain l4.

Shafting I8, a speed-reducer l9, and belt 20 serve to drive the lower sprocket l3 from the same mechanism which operates the cementing machine rollers, and the entire assembly is so constructed that rack R will move upwardly at a speed which will make it possible for the operator to remove a sole from rollers 3' and insert it in a shelf II without reaching upwardly or downwardly an undue distance from the level of the rollers. In other words, as the upper shelves II are filled, the rack is moved upwardly so as to bring lower shelves into the height zone most convenient for the deposit of soles upon the rack by the operator.

An electric switch, as indicated at 2|, includes a trigger 22 extending into the path of the rack and when the rack has reached a predetermined height it will engage trigger 22 to operate switch 2! to open the circuit of the driving motor and, if desired, to sound a warning which will direct the attention of the operator or an attendant to the fact that the loaded rack should be removed from the framing and chain and an empty rack substituted therefor.

The device is simple and economical in construction and provides a substantial convenience for the operator who can dispose of cemented soles more readily and with less likelihood of smearing cement on the smooth portions of other soles than if he had to deposit each sole at a different level than the one before.

Obviously the device is not limited to the handling of shoe soles following a cement operation but, with suitable modifications, may be adapted for use in connection with other shoe manufacturing operations.

It is not necessary for the rack elevating mechanism to be operated by the cement roll drive. Separate motor and shafting may be provided for this purpose. The drive arrangement and other details of the structure shown are relatively unimportant and may be varied substantially without departing from the spirit of the invention and the exclusive use of all those modifications coming within the scope of the claims is contemplated.
